Photographic light-sensitive material hardened with a vinylsulfonyl compound

Abstract

A photographic silver halide light-sensitive material having at least one hydrophilic colloid layer containing (a) gelatin and/or a gelatin derivative and (b) at least one compound represented by the following general formula (I) or (II): ##STR1## wherein Y represents a vinyl group; A represents a divalent group; R, which may be the same or different, each represents a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms; and n is 0 or 1. The compounds of the general formulas (I) and (II) are novel class of gelatin hardeners which are particularly suitable for use in silver halide photographic light-sensitive materials.

What is claimed is: 
     
       1. A photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer, with at least one hydrophilic colloid layer thereof containing (a) gelatin and/or a gelatin derivative and (b) 0.1 to about 10 wt% based on the weight of dry gelatin or derivative of at least one compound represented by the following general formula (I) or (II): ##STR6## ##STR7## wherein Y represents a vinyl group; A represents a divalent cyclic or acyclic hydrocarbon group having 1 to 10 carbon atoms, one to three of which carbon atoms can be replaced by a hetero atom; R, which may be the same or different, each represents a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms; and n is 0 or 1. 
     
     
       2. The photographic light-sensitive material as claimed in claim 1, wherein said divalent group represented by A is a straight or branched chain hydrocarbon group having 1 to 5 carbon atoms. 
     
     
       3. The photographic light-sensitive material as claimed in claim 1, wherein said hydrophilic colloid layer is a gelatin-containing layer. 
     
     
       4. The photographic light-sensitive material as claimed in claim 4, wherein said compound is present in said gelatin-containing layer in an amount of from 0.5 to 5 wt%, based on the weight of the dry gelatin. 
     
     
       5. The photographic light-sensitive material as claimed in claim 1, wherein said R is a hydrogen atom or a methyl group. 
     
     
       6. A method of hardening gelatin in a photographic light-sensitive silver halide material which comprises treating the photographic light-sensitive silver halide material with a compound represented by the following general formula (I) or (II): ##STR8## ##STR9## wherein Y represents a vinyl group; A represents a divalent group; R, which may be the same or different, each represents a hydrogen atom or a hydrocarbon group having 1 to 4 carbon atoms; and n is 0 or 1.
